Magnetocardiograms

Measuring the electrical activity of the heart is crucial for medical diagnostics. The conventional method, the electrocardiogram (ECG), picks up these electrical signals directly using electrodes attached to the skin. This approach faces several challenges: it can be affected by various body tissues and fluids, requires setup time for electrode placement, and carries the risk of skin irritation, discomfort, and issues related to poor electrode contact, often caused by sweat or patient movement. Additionally, accurate readings with ECGs can be dependent on sensor alignment or exact positioning.

Magnetocardiograms (MCGs) offer an alternative approach by using magnetic-field quantum sensors. Unlike ECGs that detect electrical signals directly, MCGs measure the magnetic field generated by the electrical activity of the heart muscle cells. This method has distinct advantages: it is a contactless application, meaning measurements can be performed without direct skin contact, even through clothing, and with virtually no setup time. The superior measuring technology of quantum sensors used in MCGs helps ensure accurate readings regardless of sensor alignment or exact positioning.

This allows for the detection of even subtle signs of serious conditions, such as heart attacks or oxygen deficiency. The contactless application improves efficiency, saves valuable time, and reduces discomfort and issues associated with electrode contact. The technology could be used in various settings, including mobile devices for home monitoring, or even for monitoring the heart activity of the driver of a vehicle by placing the sensor in the seat.
